Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

Advanced Science, EarlyView.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...

AMP-activated protein kinase – not just an energy sensor [version 1; referees: 3 approved]

F1000Research, 2017
Orthologues of AMP-activated protein kinase (AMPK) occur in essentially all eukaryotes as heterotrimeric complexes comprising catalytic α subunits and regulatory β and γ subunits.

Honeysuckle‐Derived Nanovesicles Regulate Gut Microbiota for the Treatment of Inflammatory Bowel Disease

Advanced Science, EarlyView.
This study explores honeysuckle‐derived nanovesicles (HNVs) for treating inflammatory bowel disease. Orally administered HNVs alleviates colitis in mice by repairing the gut barrier, reducing inflammation, and restoring a healthy gut microbiota.

Confocal Absorbance‐Activated Droplet Sorting (cAADS) for Enzyme Engineering

Advanced Science, EarlyView.
A custom confocal absorbance‐activated droplet sorting (cAADS) platform is presented, which confines illumination and detection to a small area on the “droplet plane”, enabling enhanced sensitivity at ultrahigh throughput. System performances and versatility are demonstrated by screening Bilirubin Oxidase encapsulated in 10 pL droplets at 5.4 kHz ...

MicroRNA‐Enriched Plant‐Derived Exosomes Alleviate Colitis by Modulating Systemic Immunity, Metabolic Homeostasis, and Gut Microbiota

Advanced Science, EarlyView.
Herbal medicine, with its multicomponent and multitarget potential, is often studied primarily for traditional forms, especially phytochemicals. Currently, ulcerative colitis lacks natural, low‐toxicity therapies, yet emerging research highlights plant‐derived exosomes as a promising option.

Xylose Metabolism Perturbation in Yarrowia lipolytica for Efficient Succinic Acid Bioproduction from Lignocellulosic Biomass

Advanced Science, EarlyView.
This study engineers Yarrowia lipolytica to produce succinic acid (SA) from lignocellulosic biomass. Adaptive evolution and multi‐omics analysis identify regulators that alleviate xylose metabolic disorder. Multi‐copy integration of xylose metabolic genes resolves redox imbalances from a futile fatty acid cycle, producing high‐titer SA from corn stover

ATP Hydrolysis by α‐Synuclein Amyloids is Mediated by Enclosing β‐Strand

Advanced Science, EarlyView.
Pathological amyloids have been considered chemically inert until recently. Here it is shown that α‐synuclein amyloids catalyze the hydrolysis of the universal energy molecule, ATP. The cryo‐EM structure of the complex reveals an additional β‐strand (purple) that encloses the ATP‐binding site. Within the cavity, several lysine residues are required for

A single nucleotide polymorphism produces different transcription profiles in Campylobacter jejuni’s cysM

Frontiers in Microbiology
A single nucleotide polymorphism (SNP) in the 126 bp untranslated region (UTR) directly upstream of Campylobacter jejuni’s cysM (cysteine synthase) results in significant effects on gene transcription.
